Abstract
UN CONMUTADOR DE TELECOMUNICACIONES PROGRAMABLE TIENE SOPORTE AUTOMATICO DE TARJETAS DE LINEA PARA PROPORCIONAR REDUNDANCIA COMPLETA. EL CONMUTADOR TIENE TARJETAS DE E/S QUE TERMINAN LAS DISTANCIAS DE TELECOMUNICACIONES EXTERNAS. CADA TARJETA DE E/S PASA LOS DATOS DESDE SUS DISTANCIAS A UNA TARJETA DE LINEA. CUANDO LA TARJETA DE LINEA FALLA, LA TARJETA DE E/S CONMUTA LOS DATOS EN UN BUS DE E/S QUE ESTA CONECTADO A UNA TARJETA DE E/S DE RESERVA. LA TARJETA DE E/S DE RESERVA CONMUTA UNA TARJETA DE LINEA DE RESERVA EN CONEXION CON EL BUS DE E/S DE MODO QUE LA CORRIENTE DE DATOS SEA ENTONCES SERVIDA POR LA TARJETA DE LINEA DE RESERVA. LA TARJETA DE LINEA FALLADA PUEDE ENTONCES RETIRARSE Y SUSTITUIRSE. TODAS LAS TARJETAS DE E/S ESTAN UNIDAS AL BUS DE E/S PARA QUE LA REDUNDANCIA PARA TODAS LAS TARJETAS DE LINEA ACTIVAS QUE UTILICEN EL MISMO PROTOCOLO DE SEÑALIZACION ESTEN PROVISTAS CON UNA UNICA TARJETA DE LINEA DE RESERVA. CON BUSES DE E/S MULTIPLES, TARJETAS DE E/S DE RESERVA Y TARJETAS DE LINEA DE RESERVA, ES POSIBLE UNA REDUNDANCIA MULTIPLE. FINALMENTE, EL FALLO DE UN MODULO DE LINEA UNICA DE UNA TARJETA DE LINEA PUEDE SER MANEJADO MEDIANTE LA CONMUTACION UNICAMENTE DE LA DISTANCIA SERVIDA POR ESE MODULO A UNA TARJETA DE LINEA DE RESERVA. LAS DISTANCIAS DE DIFERENTES TARJETAS DE E/S PUEDEN SER SERVIDAS POR DIFERENTES MODULOS DE LINEA DE UNA UNICA TARJETA DE LINEA DE RESERVA, Y PUEDEN ESTAR CONECTADAS A LA MISMA TARJETA DE LINEA DE RESERVA MEDIANTE EL MISMO BUS.
